To all whom z' may concern: f

Be it known that I, FREDERICK A. HART, a citizen of the United States, residing in Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Combined Type-Whiting and Computing Machines, of which the following is a specification.

My invention relates to computing machines, and is herein illustrated as applied to a combined typewriting and computing machine of the general type disclosed in the United States patents to Hans Hanson, No. 816,319, dated March 27, 1906, and No. 905,421, and No. 905,5@2 dated December l, 1908.

Y This application is a division of No. 833,357, which is a division of No. Ll66,336, filed December l0, 1908.

In said patents the numeral keys of the typewriter, as they are operated, set up on computation bars the digits written-by said keys, andthe digits thus set up and written are later 'carried into computing or dial wheels. Since there are only ten numeral keys on the typewriter, there is provided a separate computation bar for each of the computing wheels, and the typewriter carn riage at any moment determines cnw-hat bar the numeral key then operated will set up a digit. 'The digit is thus set up by de* pressing the proper one of a set of unit or digit pins on the computation bar, and after a. number has been completely set up by depressing a pin on each of several bars, the.

bars are driven forward-bv a general operator which includes a cross-bar, said crossbar coming forward, striking the ends of the depressed pins, and driving the bars thereby each toan extent depending on the location of the depressed pin thereon. The computation bars include racks on their forward ends, and these racks serve to turn the computation wheels as above described.

According to my invention, the computation bars may be shifted to pin-setting position by a dog which is adiustably positioned at any one of ay number of letterspaces on the typewriter carriage. Said.

dog, as the typewriter carriage travels along, passes under and lifts one after another a series of Jacks which are connected to said computation bars, in such a way l that in lifting each pick, the dog will lift or shift its computation bar so as to bring the pins thereon to position within the range of pin-setting linkages operated by the numeral keys of the typewriter. Each pin-setting linkage is operated every time its numeral key is depressed, but the linl ages are ineffective on the pins unless some thereto. Fig. 2 is a side View of the same,

In the No. 5 Underwood typewriting machine character keys 4 and numeral keys 5 depress their key levers 3, to cause the typebars to -swing upwardly and rearwardly against a platen lewliich is supported in the usual carriage 2. Said carriage includes the usual escapeinent rac; 22 by which the carriage is fed along one letter-space at a time by the operation of the keys. As the typewriter carriage travels along, its pointer 2st. shows at any moment on the sca-le 23 the letter-spaceat which the carriage is standing.

The typewriter frame is detachably mounted upon the case 30 of the computing mechanism; and said computing mechanism includes the devices on which the numbers i are temporarily set up by the numeral keys,

the computing wheels, and various tenances of these devices.

Whenever a numeral key 5 is depressed to print-it at the vsaine time automatically operates a pin-setting linkage which may cause a pin 05 to be set up on any oin nine register' or computation bars c. These bars are utilized for selecting the denomination of computations and may be regarded as decimal order bars. `Said decimal order bars c usually stand in the position seen in Fig. l1, in which their pins 05 are clear of pin-setting linkages which include unit bars bl. Said decimal order bars are, however, in a manner hereinafter described, raised one at a time into the position seen at Fig. 2, wherein one is raised so that its pins are within the range of the pin-setting barsv Z, with the result that when any numeral key is depressed, its pin-setting bar 57 will deappurpress a pin c5 on the elevated computation bar c, thereby setting up the digit represented by that key on that bar. One such pin is shownas being set in Fig. 2. There are typewriter lcarriage p -or jacks f1 under which said tappet passes.v

nine such pins c5 on each register bar, mounted in a thickened portion of the bar and yieldingly held in position by springpressed balls c6.

The connections for raising the decimal order bars c to the position seen in Fig.'2 include, a denomination-selecting dog, or tappet i mounted on a 'bracket f4 on the 2, and a series of levers By means or" its upper face which is beveled to form a cam surface, as seen in Fig. l, the tappet engages the beveled cam ends of the jacks andgraises them one after another so that each jack swings around.l its pivot fla, whereby the rear end of the jack will -v depress its wire or rod fl, causing the lower 50 end of said rod to rock a lever fle to lift its decimal order bar c to the pin-setting position seen in Fig. 2. Between the levers fle.

and the decimal order bars 0 is a transposition device to enable the typewriter carriage, as it travels to the left, to bring the computation bars successively into 'pin-setting position, beginning with the left-hand 'ba-r. Such a transposition device is necessary to give this result, because the numbers on the typewriter are written first with the left-hand digit, than with the next to the right of that, andso on; and it is essential that the computations in the computing device begin on the corresponding decimal order ber 'at the lett, and then on the next bar cent to the lugs f2s.

imanes to the right of that, and so on, so that numbers written in any particular column will be computed inthe corresponding column, and in the same order in the computing de vice.

T he transposition device includes a series of transverse linkages at the rear of the machine, each linkage including a parallel motion device which includes an upwardly eX- tending lug fn on a link 7'23, there being one of such lugs underlying each of the computation bars 0, and therefore one linkage for each' of said computation bars. Each of these linkages is adapted to be operated by one of the levers f1 said levers, as will be seen fromliigs, ll, and 1G, are lsuccessively oi' greater lengths, so that the forward ends ci' said levers each operate only one of the linkages, each linkage being provided with a downwardly extending lug f2s, which overlies the front end ofits lever fw, and by which the lever operates the linkage. The lugs f2s are of sufficient height so that there will be no possibility of any lever f striking any other linkage in its movement upward. When the rear end of said lever is depressed by its rod f1? when operated by the dog on its carriage, as best shown in F ig. 2, the lever f1 will raise the bar and cause its lug )C29 to lift the cornputation balr to the position shown in Figu2.

The arallel motion device for each linkage includes a bell crank f2* at each end of the link ,im and attached to an arm reaching downwardly freni saidlink, sain bell cranks each being journaled on-'a tie-rod im, and said belly cranks having their other ends connected by a second link f. The decimal order bar raising links are normally held in theirl lowest position byV coil springs f2?,

ends, and are held down by flat springs c* so 'that they Anormally rest on, or are adjawhen the bars c are raised by their linkages f2", and the teeth of the comb are long enough to permit such raising.

The keys 5 operate their pin-setting linkages bl by means of stems or push rods b, each of which, as its key descends, will strike its rock arm on the forward end of a linkage-operating rock shaft 65. These rock shafts b5 are each provided with a rock arm 512 fast thereon, said rock arm ending in a fork which engages a Wrist 513 on a link b9 forfrniug part of a parallel motion device for its pin-setting linkage 57.

As the key stem b rocks its rock yshaft b5, it swings the link to theleit so as to rock a bell crank Z210 at each end thereof, said bell cranks also carrying the pin-setting or unit bar 57, and the form of the bell crank is such. that the short vertical 'arms thereof These springs yield' move the link b9 almost horizontally, while the long horizontal arms thereof swing the pin-setting bar bl nearly vertically.

The system of linkages including the bell cranks 51, links 59 and bars bl are assembled in a frame b2, on rods En, on which the bell i cranks om are mounted, and said frame also includes tie-rods into whicn slots os are cut, forming guides for the pin-setting bars 57. rlhe frame o2 is mounted on the case 30, and said frame 7a2 comprises bars which are notched at 2b (Fig. l5) for engagement with .the depressed ends of supporting strips 2C rigidly secured on the inside of the case 30. The pin-setting or unit bars bl are held in their normal elevated position clear of the pins c5 by coil springs'b which are anchored in the frame b2.

lilith the construction described, it is evi-y dent that the depression of one of the numeral keys will result in the depression of the corresponding pin-setting or unit bar ,7)7. It will also be noted, particularly by reference to Fig. l5, that a very considerable portion of the downward movement of the depressed numeral key takes place before the key brings its push bar Z) into engagement with the corresponding rock arm lf. It will also be noted that the up-per arms of the bell cranks 51 are very short ascompared with the lower arms thereof, so that a very small portion of the final downward movement of a numeral key is required to e'ect a considerable downward movement of the corresponding pin-setting bar.

One special object of this invention is to provide for a very light touch and for the possibility of operating the numeral keys in very rapid sequence. This is obtained by having the numeral keys operate in the manner described, which enables the momentum gathered by a type-bar in the early part of its stroke to do practically all of the work of operating` its pinsetting bar 57. rl`he bars at their lower ends are guided in openings 518 in a plate formed by a forwardly projecting ilange on the frame b2.

When a number has been written and has been set up on the decimal order bars c., it is carried by a general operator into the digit-bearing computing wheels a. at the front of the machine, which wheels are supported on a cross shaft al having bearings (rising from the bottom ef the computer case 30). For driving its wheel, each decimal order bar Vc has at its forward end, formed integrally therewith, a rack comprising teeth which mesh with the pinion 'a2 f on its computing wheel a.. The decimal order bars c have their racks constantly in mesh with the pinions a2, with theresult that when the geheral operator moves forward, a cross'bar c", formingI part of said 'general operator, will strike the projecting ends of any depressed pins cA and drive the computation bars thereby, so that each bar i turns its pinion to an extent depending on the location of the pin depressed. Said gen-y eral operator forms an operating carriage which includes side bars cT and a cross bar cw, which form a rigid frame, which is manually driven bv a handle c1J at the right of the machine. For driving the general operator from this handle, the handle is fast to a shaft cl2 extending across the machine and provided at each end with a toothed segment c. Said segments mesh with idle pinions el, which pinions in turn mesh with racks cut in the side bars c of the general operator. To drive the general operator, the handle 013 is pulled forward, thus driving the general operator forward, and causing saidgeneral operator to pick up the computation bars c, one after another, through depressed pins The general operator slides in guide bearings c on the sides of the case 30 and is arrested at the end of its forward stroke by stops in the form of set screws c55. lTo ret-urn the general operator, the handle c is moved rearwardly, and the. cross bar G10 of the general operator engages lugs c3' on the forward ends of the computation bars, and pushes said bars rearwardly. @n this return movement, the pinions c2 turn idly on the computing wheels a because of one-way clutches, not shown, between the computing wheels .c and their pinions a2.

At the very end of the return stroke of the generaloperator, the set pins c are all unset or returned to normal position. For this purpose there is provided under the pins where they normally stand, a restoring plate c which is raised against the under side of the computation mebmbers c at the end of the return stroke of the general operator, thus lifting the pins c5 to their normal position. For accomplishingl this, the general operator is provided with a springheld cam-acting dog 052, which, on the return stroke of the general operator, rides under and lifts an arm 051, fast on a rock shaft 043 which forms part of a parallel motion device for the pinfrestoring plate c4". lDuring the forward stroke of the general operator, this dogl 052 is swung idly out of the way against the tension of its spring. 0n the return stroke of the zgeneral operator,

however, the cam face of the dog 052 mo' mentaril-y lifts the arm '051, thereby inomentarily lifting the platform c. To allow for this motion, the dog 052 pivoted on an extension of the bar c7 of the general operator. and includes an arm comprising` a top which is normally drawn by the spring of the dog against a stop clip c5" fast tc the betteln of the general operator. The pin-restoring plate c is pivoted on rock arms forming of a parallel motion de vice which includes twc parallel shafts c,

each having arms thereon, to which is riveted at'it's inner end to the central portion of the platform 047, and its free end is made adjustable relatively thereto by a set screw c5.

In order to prevent the computation bars c from rising when the pin-restoring plate c is raised, the mechanism includes a holdextent farther,

ing bar 1O which is swung over shoulders on the rear ends of the computation bars at the moment the pin-restoring plate c is operated. This bar 1o is moved to its effective position by connections which will be described later. The general operator itself is arrested at the end of its rearward stroke by a stop '57 on the case 30, said stop being located in the mounted on a side bar c7 of the general operator.

When a number has been carried into the computing wheels and then another'nuinber is added thereto, 'it is necessary, if any wheel turns from reading 9 to reading 0, to provide that the adjoining wheel to the left will be advanced one unit space, thus making` a carry-over, as is ordinarily done mentally in addition. To accomplish this the machine is provided with carryover devices of the general type shown in the aforesaid Hanson patents. Each computing wheel is provided with a single carry-over tooth, which, when the comput- 9 to 0, will give an adjacent carry-over pinion a slight turn, and said pinion, on the return stroke of the general operator, is turned to a considerablewith the result that it turns the adjacent computing wheel one unit space, thereby completing the carry-over, as particularly described in patent to Hanson, No. 816,319, in connection with Figs.

42, 43, 44 of said patent. The computing wheels are provided with spring detente a6 mounted. on a transverse rod a7, and the carry-over pinions areprovided with similar detents whih may have for springs, the springs used for the detents a7.

When a carry-over pinion has been set on the forward stroke of the general operator by a computing wheel a, it brings its sixtoothed wheel a9 into the position described in the said Hanson Patent No. 816,319, where its toothed driver L15 will drive it on the return stroke of the general operator, and in so being driven, the three-toothed pinion a1 will turn the adjacent computing wheei a one unit space. There is a driver 615 for each carry-over wheel and they are spiing wheel turns from path of a set screw adjustably -grooves in said rally mounted on a shaft w14 extending across the machine, and said shaft is driven by a pinion meshing with the side rack of the general operator, said pinion meshing with a pinion a1 which vis on the driving shaft a, but is connected thereto by a oneway clutch, insuch a manner that the shaft a stands idle on .the forwardstroke. of the general operator, but is rotated on the rey turn stroke thereof.

In order to holdthe computation bars against rising` when "the pin-restoring platform rises, a bar. 10, as has been stated, is caused to bemoved backward over the rear raised ends of the computation bars, and this movement 'is effected by the lcarry-over drive shaftam. The connections for accomplishing this include the cam plate 21 fast on said shaft (L11 which co erateswith the follower 17, sai-d follower normally lying against the innermost portion of said cam. During the return stroke of the general operator, said f ollower 1'7 is drawn forward so as to move the holding bar 1 backward, and for this purpose tie front having an abrupt end -just beyond which the follower 17 normally rests. Said follower 17 is carried on a shaft 18 and is connected to operate the holding bar 1 a link 16, the rear end of which has a shoulder 15 catching behind a transverse bar 14, which is carried on depending arms 13 of a rock shaft 12, said rock shaft carrying the holding bar 1 by upstanding arms 11. Said holding bar 1o is normally held clear of the computation bars c by a light spring 19 which draws it forward. The link 1G is guided in an angle bar 301 of the casing 30. l

The denomination-selecting dog f is pivoted on a block or carrier f1, so that on returning of the typewriter carriage to begin a new line, said dog may swing backward on its pivot and pass the jacks-f1 easily.

or block on which the dog f is mounted 1s in front itself pivotally mounted on a rod f5 of the place normally occupied by the dog f so that the carrier may be swung upward around the rod f5 in front and out of the way of the jacks f1, as shown in dotted lines at Fig.4 3. This rod f5 is carried on brackets f1 on the typewriter carriage, and the cardetained on said rod in either its effective or ineffective position by a springpressed detent f1 which engages one of two rods. Then the carrier fl is swung down to hold the dog f so that it will pass under the jacks f1, the cairier f rests on a supporting bar f6 carried on said brackets, and a tooth fs on the carrier engages with teeth or notches on said supporting bar f6, thus holding the carrier'against cam 21 has a snail slipping as the typewriter carriage feeds along, andlcarries the dog past the jacks These notches are set at letterspace intervals and are 'so located, that when the typewriter carriage is at rest, the dog fwill stand under one of the jacks f1, and hold it elevated. To facilitate correct adjusting of the dog f at the desired letter-space in the travel of the carriage, there is provided adjacent the rod f5 a scale plate fn, which cooperates with a pointer f1 Jfast on the carrier f7, said pointer curved under the rod f5 and overlying the scale. Said scale is graduated to correspond with the scale 23 at the front of the typewriter carriage. The carrier f7 with its dog f can lee removed Jliroin the bar fby slipping the carrier to the reduced end 7c3'l of said bar and lifting the carrier therefrom.

The jacks f1 are carried in a frame supported on a pair of rearwardly and up- 'wardly extending laterally-spaced arms f2 which are attached to the typewriter frame and rigidly support a transverse rod f3. The levers or jacks f1 are jou-riialed on a transverse rod 7:13 mounted on plates fm carried bythe rod f3, and the jacks normally rest on'a rod f1* eiitending between said plates fm. The rod 7m is preferably notched to aid in spacing the index or jacks which are also spaced by suitable collars or washy ers on the rod fla. rlhe rods f13 and ,ai are adjustable to correctly locate the liacks f1 with respect to the denominatio-n dog f. The rods f are detach-ably supported in a notched guide plate f, against which they are held by a cooperating bail f1", said bail being journaled on the rod fla., The casing fu extends rrom the plate 7m to the computer case to protect the rods 7'15 and said Y rods are connected to their levers f1 by means of coupling heads f, which are split and provided with threaded seats into which the lower ends of the rods are screwed, and by which the rods. aie rictiiinally held against accidentalrotation. The lower ends of said coupling heads arebifurcated so that they straddle the rear ends of said levers, and they are provided with pins fm that loosely rest in notches or open seats f formed in the rear ends of levers fm.

Normally tne bail fw rests on the plate f, and holds the rods f1 in place against `said plate. lllhen, however, the bail is swung up., the rods may be removed and lifted out of the open seats f2* on the levers fw.

t. will be noted that in the operation of the machine, the keys will, in the adding zone, cooperate with the traveling paper carriage and index or set up a preliminary representation of a number on the denoinination bars c, and later that the numbers thus set up are carried into the adding or computing wheels by a general operator or Scope of the invention, and portions of the improvements may be used without others.
